Abstract: L'invention concerne un catalyseur de craquage d'hydrocarbure de pétrole, qui contient de la zéolithe Y de terre rare, ainsi qu'un procédé de préparation correspondant. L'invention se caractérise en ce que ladite terre rare contenant la zéolithe Y présente une teneur en terre rare intracristalline allant de 4 à 15 % en poids sur la base de l'oxyde de terre rare, une constante de cellule unité originale de l'ordre de 2,440 à 2,465 nm, et une dimension de cellule unité compensée supérieure à 2,435 nm après vieillissement dans des conditions extrêmes de 100 % de vapeur, à 800 °C, pendant 17 heures. Le procédé de préparation dudit catalyseur comprend les étapes suivantes : sécher la terre rare contenant la zéolithe Y, de sorte que sa teneur en eau soit inférieure à 10 % en poids ; introduire un tétrachlorure de silicium gazeux véhiculé par de l'air sec, dans un rapport en poids du tétrachlorure de silicium à la zéolithe Y de  0,1-0,9:1 ; purger avec de l'air sec après réaction ; et laver l'eau décationisée afin d'éliminer les produits secondaires solubles résiduels pour obtenir la terre rare contenant la zéolithe Y ; puis la mélanger avec les matières premières contenant de l'argile et un agglomérant ; battre, pulvériser à sec et façonner. Ledit catalyseur peut réduire la consommation de zéolithe de 5 à 25 %, comparativement aux catalyseurs utilisés pour craquer des huiles lourdes, et réduire les oléfines préparées selon l'art antérieur. Ledit catalyseur présente une activité élevée, une stabilité hydrothermique, un pouvoir élevé de transformation d'huiles lourdes et une bonne sélectivité en termes d'essence, de gaz secs et de coke. Dans le produit, la teneur en oléfine de l'essence peut être abaissée efficacement.

Patent WO-0060663-A1 (WO)
Inventor: NEU ACHIM
IPC: H01L21/56
Filed: 2000-03-31
Abstract: The invention relates to integrated circuits having a protective layer of diamond-like carbon and to a method of producing said circuits. Security-relevant data, such as access codes, passwords, personal data or algorithms, are increasingly stored in integrated circuits. Furthermore, it is of considerable interest to keep such information secret. To date there are no known, sufficiently reliable ways of preventing mechanical access being gained to an integrated circuit. The present invention therefore provides a coated integrated circuit which presents a printed conductor structure and a diamond-like carbon layer (DLC layer) on at least part of the printed conductor structure. The DLC layer can contain between 10 and 30 % hydrogen as well as additives selected from nitrogen, silicon, oxygen and fluorine.
Patent WO-0123108-A1 (WO)
Inventor: BAYER THOMAS
IPC: B07C3/14
Filed: 2000-08-08
Abstract: The invention relates to the sorting of parcels in several sort passes. In order avoid the need to read the address in each sort pass and in order to avoid printing a machine-readable identification code on each  parcel, further elements which are characteristic of the parcels are established during a first sort pass and memorised together with the distribution codes established during the reading process. During subsequent sort passes, the characteristic elements are simply measured and compared with the stored features. Matching parcels are assigned corresponding distribution codes. A special conveyance system with defined sequences guarantees that only n parcels have to be compared at a time, n representing maximum multiple delivery rate.

Title: Injection moulding - using varied pressures to prevent mingling of cladding and foam core materials
Inventor: SCHREWE KLAUS
IPC: B29C44/04
Filed: 1972-01-27
Abstract: Designed for the injection moulding of a cladding material, followed by a foam core plastic two separate pistons are used with a common channel into the mould. The piston cylinders are of different diameters so that under a common hydraulic control the pressure is greater on the cladding material than on the foam component. On passing through the common channel, a portion of the cladding material is allowed to rise into the foam feed channel, which is then passed in when the foam is injected. Mingling of the foam component with the cladding material, which could lead to a faulty and unstable moulding, is prevented.
